Your stock intake plug is 92174, same as the Hemi. The good one range colder plug for that is 7787 or 3672 (can't see a difference between these two)

Exhaust stock plug is 97606, a double platinum plug. Should be able to use the 5987 for those!

This would take you from heat range 5 up to heat range 6 on both and they have all the same specs as the stockers, just one step colder!

You can go on ngk.com and put the plug part numbers in to compare all the specs.
Are you sure? Where'd you get that info?

I didn't check the info you posted but these are the stock plugs (bosch) from what I've found:

Intake:
Part # FR8TE2
Yttrium enhanced for longer performance life
Also says it has 2 ground electrodes
Center Electrode Core Material: Nickel-Yttrium and Copper
Center Electrode Tip Material: Nickel-Yttrium
Ground Electrode Tip Material: Nickel-Yttrium and Copper

Exhaust:
Part # FR8TI332
Center Electrode Tip Material: Iridium
Ground Electrode Tip Material: Nickel-Yttrium
